Windows 7: Acer X1301 crashes when running videos

Win HP 7 64-bit OEM.

I don't know if it is OS related or not.

When watching videos what ever the source it will make a buzzing sound and then crash for good. It is a daily thing, randomly. Always when a video is running. I added a ATI 5450 video card and it does the same.

I updated the BIOS and all drivers to the latest versions. Windows Update works well.

Any idea?

Maybe your computer is over heating clean the fans and heat syncs free from dust

Another point may be noted ... what codecs you are using ? Try Shark007's FREE Codec solutions - Windows 7 codecs and see if it is the same crashing or not.

I just tried that, although if I got him right the developer noted that the 64-bit version isn't likely to any help. I also updated the audio driver with a differet version on Acer site.

It doesn't overheat... I have the Moo0 monitor.

As your system is 32 bit (specs says so), you dont need 64 bit codecs . Even it is not compulsory for a 64 bit system, too.

After the codec installation, is it crashing till now ?

Yeah it does. After 6.5 hours of operating time it did it again. I guess that running heavy videos kills it.

I give up. Will be available for dirty cheap in classifieds.

No more Acer for me, thanks.

It isn't sold yet (although on Craigslist) but here is a funny thing. I removed the cover, played with the cables and left the cover aside. It has been running on TV tuner (WMC) with no crash for 2 days!

I wonder if it was not the 220W power supply that overheats and trips.

Fragile beasts.
